摘要
为了提高铁路运输易损件辙叉心轨的使用寿命,在大生产环境下,采取强韧化工艺进行了质量优化研究,提高了心轨的综合性能,延长了使用寿命。
In order to extend the service life of middle flog rail of wearing parts for railway, in large-scale production condition, the quality optimization with strengthening and toughening process was studied, the general performance was increased, thereby the service life extended.
